This way i can use a keyboard shortcut like “com+opt+shift+r” to trigger the action.
When i editted .zshrc file, i need to restart terminal.app, this shortcut would be very useful.
When you edit .zshrc you can run source .zshrc and changes will take effect.
i know, i just set an example, and a shortcut will be quicker when i need to do it multiple times.
when an app have no response, i can use this to restart it either, instead of "quit the app, open spotlight, type appname and then start the app".
